The seven year great tribulation, which is not found anywhere in scripture, was derived by mans misinterpretation of Daniel 9:24-27. This is what the Bible clearly reveals about the seventy weeks. From vs.24 to vs.27 was seventy weeks or 490 days (490 prophetic years when you add a day for a year principle), beginning with Ezra, Ezra chapter 1-6, rebuilding the temple to the time of the Messiah (Jesus Christ) being fulfilled in His birth, death and resurrection. In a sense it was a literal and spiritual temple that was being built. Ezra was teaching the people of the spiritual temple of God that indwelled in all that believed in God and of the coming of Messiah. There was actually a four hundred year span from Ezra till the birth of Jesus that God shut himself off from Israel because of their transgressions towards the Lord, Malachi Chapter 4, but saved a remnant that would believe in the coming of Messiah, Isaiah 10. As still today, God still waits for National Israel to repent and believe in the name of Jesus as they still follow Judaism.
Daniel 9:24-27 the Vision of the Seventy Weeks
Vs. 24 this verse shows us that the timing from Ezra to the cross was 490 days (490 Prophetic years) as within that time Ezra was reestablishing the law in Jerusalem until Jesus had fulfilled the end of transgression, made an end to sin, made reconciliation for iniquity and bring everlasting righteousness and to seal up the prophecy to fulfill parts of the law through the cross.
Vs. 25 from the time of the cross, which also means the last days, which includes what some like to separate and call The Great Tribulation, which is not mentioned anywhere in scripture and is not a separate event after the elect of God are caught up, but as the last days so we are in tribulation times until the end of the world as we know it, Acts 2:17; Hebrews 1:1,2; Matthew 24:4-31; Mark 13:24-31; Luke 21:5-36. These are just some of the scriptures that support that we will go through all things of Rev Chapter 6-21. Everyone will have opportunity to come unto salvation through Jesus Christ if they would only believe until the door of salvation is closed when Jesus returns on the last day, which after this time no one can be saved, Matthew 25:10.
Vs.26 after 434 years that end in the year AD29 shall Messiah be cut off. Jesus was crucified after he was baptized in AD 29 three and a half years later. Jesus was cut off (killed) by the people of the Romans under Vespasian their prince that the Pharisees, Sanhedrin and the high priest who have favor with that destroy the city and the sanctuary (meaning Christ) and the end thereof shall be with a flood (Gods wrath) that will put an end to abominations by desolation or in other words a ruin to evil deeds. Daniel 9:27 explains the definitions of desolation of abominations or the ruin of evil deeds. There is no actual Desolation of Abominations where a so called Antichrist (emphasis on the capitol "A") will take a literal throne, but the desolation will be when the son of perdition, being the false prophet/last antichrist, tries to take his throne in Jerusalem, Daniel 11:36-45. Gods word never defines one great Antichrist, but says there are many antichrists, 1John2:18; 11 Thessalonians 2:1-12; Revelation 11:7. The seven years that some call the seven year tribulation means three and a half years beginning with the first six seals being the beginning of sorrows (first woe). The last three and a half years starting with the (second woe) with the sounding of the first trumpet and ending with the seventh trumpet that includes everything else written in Revelations that includes the time of Christ return for His Bride in Rev 19 up to the end when Satan is cast into the lake of fire with the beast and the false prophet and ends with the new Jerusalem being ushered down as then we will be with the Lord forever.
Vs.27 the 70th seven began with Christ baptism in AD 29 and three years later at the end of the first half of the 70th seven sacrifices and offering ceased because Christ hung on the cross. From the giving of the law in 458BC when Ezra went to establish the law, or to rebuild the spiritual city right to the cross where the first 69 sevens. The 70th seven is from the time of the cross until Jesus comes back in the air to call his Bride home and for the overspreading of abominations he will make desolate, or make an end to all who would not believe.
During its long history, Jerusalem has been destroyed at least twice, besieged 23 times, attacked 52 times, and captured and recaptured 44 times. The last siege and destruction of the 2nd Temple and the wall was in 70AD as a revolt led by Titus as he broke through the walls and destroyed the Temple in Jerusalem. The wall and the Temple were never rebuilt, nor will it be in the future. The Temple mount laid waste until the Dome of the Rock was built on it in 691AD by the caliph Abd al-Malik ibn Marwan. The Islamic control over the Dome of the Rock will never surrender the original temple mount back to the Jews.
The last decree to build and restore Jerusalem, including the building of the second Temple that took 49 days/49 prophetic years, came around 538BC with the decree given to Ezra by King Cyrus. Through much oppositions the city, walls and the second Temple were completed on the third day of the month Adar, which was in the sixth year of the reign of King Darius II around 417BC as he reigned from 423BC to 404BC, Ezra Chapter 1-6. This was part of the vision given to Daniel as the full prophecy given to him is found in Daniel Chapters 9-12.
During the first six trumpets we read all the destruction that will befall earth and its inhabitants during God's great wrath being poured out into the world on those who are none of Christ as they refuse to repent. This will be worldwide which will cause much chaos and great fear in the hearts of those who have no understanding, Hosea 4:6, 7. They will be seeking a type of savior, yet rejecting the very Savior, Christ Jesus, who wants to save them.
During the sounding of the seventh trumpet they will accept this deceptive savior who is the son of perdition, 2 Thessalonians 2:3-12, who will take his seat in Jerusalem on the very Temple Mount where the Dome of the Rock sits and even now is being refurbished. He will try and rule the nations for 3 1/2 years causing all to bow down and take its mark as he promises peace and safety displaying lying signs and wonders claiming he is God. Those who refuse will be taken captive and dealt with as many Christians will either become a slave or die a martyr's death, Rev 13.
Matthew 24:29-31; Rev 19:11-21, At the end of the 3 1/2 years of the beast and its false prophet, Christ returns with His army (warring angels) from heaven and fights the final battle destroying the beast and false prophet by the spirit (word) of His mouth and the brightness of His coming, 2 Thessalonians 2:8, casting both into the lake of fire. Then will Christ destroy the remnant being those who followed after the beast out of the earth from every nation that have always followed and obeyed the beast.
Rev 20 This is the time of the gathering of the saints when Christ sends His angels out to the four corners of the earth to gather all who are His that are asleep in the grave and alive at His coming, Matthew 24:29-31 as He then binds Satan for a time so he can not interfere with the gathering. Once we are gathered to Him Jesus lets Satan loose for a time to gather his army, which I believe to be his demonic angels, against the camp of the saints, but God consumes his army by fire sent down from heaven and Satan is then cast into the lake of fire. All those who have now been slain by Jesus are gathered with the rest of the dead and face God's final judgment as their names are not found written in the Lamb's book of life and are cast into the lake of fire.
Rev 21:1 And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea. 2 And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband. 3 And I heard a great voice out of heaven saying, Behold, the tabernacle of God is with men, and he will dwell with them, and they shall be his people, and God himself shall be with them, and be their God. 4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away. 5 And he that sat upon the throne said, Behold, I make all things new.
